The minimum \(\Gamma_{r, n-r}\) of positive values of non-homogeneous indefinite quadratic forms of type \((r, n-r)\) is defined as the infimum of all constants \(\Gamma>0\) such that for any indefinite quadratic form \(Q\) of type ( \(r, n-r\) ) and determinant \(D \neq 0\) and any real numbers \(c

A conjecture of G. L. Watson asserts that the two-sided infimum of the values of a non-homogeneous real indefinite quadratic form in \(n\) variables, obtained when the variables range over all integral values, is an invariant under the signature modulo 8. There is an analogous conjecture by Bambah,

Results are obtained on orbit-closures under these actions and they are applied to describe a class of binary quadratic forms Q such that the sets QรฐZ 2 รž

Both positive and negative plasma desorption mass spectra of the three-dimensionally non-molecular material [ Cd(SC,H,-2-CH3)2] contain fragment ions directly related to the lattice structure of the material. Fragment ions are observed which correspond with [ CdSC,H, I +' and [ CdS,C,H, I -' which d
